About the Defiant Aircraft Defiant

The Defiant is an American light-sport aircraft designed and manufactured by Defiant Aircraft, a small general aviation company. Built to meet the FAA's LSA category requirements, the Defiant is restricted to a maximum takeoff weight of 1,320 pounds and features a single piston engine driving a fixed-pitch or ground-adjustable propeller. The aircraft targets the recreational flying market, offering an economical entry point for pilots seeking simple, affordable flight operations under sport pilot privileges.

Like most LSA designs, the Defiant emphasizes straightforward handling characteristics and modest performance. Its stall speeds remain well below the LSA regulatory ceiling of 45 knots calibrated airspeed in landing configuration, making it accessible to lower-time pilots. The type's never-exceed speed and structural cruising speed fall within the typical LSA envelope, balancing performance with the category's emphasis on safety and simplicity. Construction likely employs composite materials or aluminum tube-and-fabric techniques common to the LSA segment.

SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
